SEISMIC FRAGILITY ANALYSIS OF STEEL STORAGE TANKS
Proceedings of the 5th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2015 Earthquakes can cause significant damages to industrial liquid storage tanks resulting in losses of functionality, fires or environmental contamination due to the leakage of hazardous chemicals. Typical damages of ground supported tanks during past earthquakes were in the form of cracking at the corner of the bottom plate and compression buckling of ...

Analysis of Seismic Fragility Functions of Highway Embankments
Periodica Polytechnica Civil Engineering, 2020 Vulnerability assessment of structures is a vitally important topic among earthquake engineering researchers. Generally, their primary focus is on the seismic performance of buildings. Less attention is paid to geotechnical structures, even though information about the performance of these structures (e.g.

Seismic Fragility Analysis of Structures Based on Adaptive Gaussian Process Regression Metamodel
Shock and Vibration, 2021 Metamodel-based seismic fragility analysis methods can overcome the challenge of high computational costs of problems considering the uncertainties of earthquakes and structural parameters; however, the accuracy of metamodels is difficult to control.

Seismic Fragility Analysis of Bridge System Based on Fuzzy Failure Criteria
Advances in Civil Engineering, 2019 In the traditional bridge seismic fragility analysis, the criterion for judging the structural damage state is clear. That is to say, when the damage index exceeds a specific value, the structure is judged to enter the new damage state.

Seismic fragility analysis using stochastic polynomial chaos expansions
Probabilistic Engineering Mechanics, 2023 Within the performance-based earthquake engineering (PBEE) framework, the fragility model plays a pivotal role. Such a model represents the probability that the engineering demand parameter (EDP) exceeds a certain safety threshold given a set of selected intensity measures (IMs) that characterize the earthquake load.
